That's semi-compact for a .40S&W that's for sure and a great answer to the question, but I would think the Kahr PM40 is smaller
9mm - comparing a Glock 26 subcompact size to the Kahr CM9 - is exactly what we did at the range on Friday. Not even close. The Glock is just real pudgy. Great gun, real capacity - but way huge for jeans pocket carry.
